Use of proceeds of refunding public securities

(1) The proceeds of refunding public securities shall either be immediately applied to the retirement of the public securities to be refunded or be placed in escrow in any state or national bank within the state which is a member of the federal deposit insurance corporation to be applied to the payment of the public securities upon their presentation therefor; but, to the extent any incidental expenses have been capitalized, such security proceeds may be used to defray such expenses; and any accrued interest and any premium appertaining to a sale of refunding public securities may be applied to the payment of the interest thereon and the principal thereof, or both interest and principal, or may be deposited in a reserve therefor, as the governing body may determine. (2) No such escrow shall necessarily be limited to proceeds of refunding public securities but may include other moneys available for its purpose. Any escrowed proceeds, pending such use, may be invested or reinvested in securities meeting the investment requirements established in part 6 of article 75 of title 24, C.R.S. Such escrowed proceeds and investments, together with any interest to be derived from any such investment, shall be in an amount at all times sufficient as to principal, interest, any prior redemption premium due, any charges of the escrow agent payable therefrom to pay the public securities being refunded as they become due at their respective maturities or due at designated prior redemption dates in connection with which the governing body of the issuer shall exercise a prior redemption option. No purchaser of any public security issued under this article shall in any manner be responsible for the application of the proceeds thereof by the issuer or any of its officers, agents, or employees.
